Mineralogisk och strukturell inverkan på fragmenteringsenergi och andel producerat finmaterial i en konkross

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Karaktärer och cases : skönlitteratur inom ledarskapsutbildning

The aim for my thesis has been to investigate how literature, or fiction, is used in management education. What books are used ? is there a literary leadership canon? What do the educators and the writers on this subject suggest that these books can teach the leaders? What are the philosophical foundations of this education? And ? last but not least ? does what the educators and writers offer respond to the needs of the businesses? My investigation shows that there is a canon in the area of management and fiction, where realistic 19th century novels, alongside with Shakespeare?s plays are dominant. Female writers and non-western writers are very underrepresented. The positive outcomes of reading and discussing these literary works that the educators and writers suggest do substantially correspond with the needs of the businesses, as presented by my sources.

Miljöutredning på Care of Haus : För och nackdelar med ISO 14001

Androidvetenskapen och den kusliga dalen: Japanska robotar som forskningsplattformar och filosofiska leksaker

The primary aim of this essay is to analyse, contextualise and problematise the scientific and technological goals of android science. The starting point of this investigation is the history of automata and man?s attempts to recreate himself by technological means. Drawing on the no-tion of boundary work this essay also analyses the efforts of the proponents of android science to establish and demarcate a new interdisciplinary field. A secondary aim of the essay is to evaluate the scientific support for the uncanny valley hypothesis and to investigate how this hypothesis contributes to android science.

"Jag bara tar ur skafferiet det som passar..." : En undersökning av hur lärare och barnbibliotekarier arbetar med skönlitteratur på lågstadiet

The aim of this thesis was to investigate the methods used by teachers and childrens' libra­rians concerning their work with fiction at the junior school level. Based on a series of qualitative interviews and by compiling a list of short summaries of literature relevant to our thesis we wished to reflect on the manner in which the respondents see themselves in their teaching roles.We also wanted to discover what problems they had in their work and what visions they held for the future. The methods used by the teachers were mainly: reading- both aloud and individually, process-oriented writing, use of fiction in thematic studies and dramatization. The teachers' aspirations for the future included a centrally situated school library and further education in children's literature. The teachers take the needs of their pupils as a starting point and build on these needs - using many years of literary teaching experience as a foundation."Booktalks" for the children and intermediaries (teachers ...)and education in books and library systems are the childrens' librarians main literaturepedagogic methods.

Vad ligger till grund för användares relevansbedömningar?: En litteraturundersökning

The purpose of this thesis is to get an improved understanding of what the bases for relevance are, when people in real information need situations make relevance judgements. In order to meet this purpose, an investigation based on research literature is performed. Four types of relevance are investigated: topical or subject relevance, cognitive relevance or pertinence, situational relevance or utility, and socio-cognitive relevance. The investigation also deals with users relevance criteria identified in fourteen empirical studies, in which the users are adults and engaged in oral, textual, and multimedia information retrieval. Finally, the connections between the user criteria found and the types of relevance are discussed.

Investigation of Syndecan-1 Ectodomain Isolated from Chinese Hamster Ovary (CHO) Cell Culture Medium

Syndecan-1 is a cell surface proteoglycan which participates in cell adhesion, differentiation, motility, morphogenesis and intracellular signaling. The two glycosaminoglycans heparan sulfate and chondroitin sulfate are covalently attached to the ectodomain of syndecan-1 via a tetra saccharide linkage sequence. However, the ectodomain can be modified having only one or neither of the glycosaminglycans attached. The glycosaminoglycans are capable of binding ligands such as fibroblast growth factors (FGFs) and support activation of receptors. The ectodomain is proteolytically cleaved from the cell surface by metalloproteinases in a process known as shedding.

Nicolaus Adam Strungks två sonator ur Dübensamlingen : Biografi-analys-edition

AbstractAnna Celander: Nicolaus Adam Strungks  två sonator ur Dübensamlingen ? Biografi ? analys ? edition. Uppsala Universitet: Institutionen för Musikvetenskap, uppsats för 60p. 2007The aim of this essay is to contribute to the knowledge of the instrumental music of the Düben Collection in Uppsala, by presenting two sonatas by a rather unknown composer, Nicolaus Adam Strungk. A great deal of the music in the Düben collection comes from Nothern Germany so one purpose has also been to investigate if even Strungk's sonatas have stylistic influenses from that region.

Förskolepedagogers uppfattningar av sitt arbete kring energiomsättningen

The aim of this study is to examine the understanding, preschool teachers, have about their work related to energy conversion in the human body. Through individual interviews, answers have been sought to the following questions: What do the preschool teachers believe they need to know about the link between food and energy? What are the different methods preschool teachers use to workwith the area of energy conversion in the human body?The results show that preschool teachers have knowledge in terms of food and its nutrients as an energy source for the body to cope with. However the more thorough and detailed questions become all the more uncertainty there is about the topic. Preschool teachers on their own initiative do bring up the topic with the children and begin conversations as well as ask questions, perform experiments and demonstrations.

The objective of this research is to unveil how respective teacher consider about the laboratory working methods in mathematics. The research even includes answers to questions such as, what approaches and attitudes the teachers have and the methods they use when instructing their students when teaching mathematics, what the materials used by the teachers are and how important working creatively is to help the students develop their logical thinking. I also looked into issues that can help understand how and why teachers use laboratory mathematics for students in young ages. As a conclusion the research showed that the teachers aim to the goal that includes helping the students understand mathematics, strengthen their logical thinking and creativity.In the method section qualitative data was used, which contained four interviews with different pedagogues that daily interact with students in elementary school. The reasons for using the method of qualitative data was to help me deeper understand and answer the specific questions I had to the pedagogues and to even compare how different pedagogues differ in their approaches and methods.

Estimation of reindeer lichen biomass by image analysis

During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.

Dräktmontering - en fallstudie av en rysk uniformsfrack

In this paper five different commonly used methods of making a mount for a costume in along term display was investigated: The shaping of a mannequin and a polystyrene dressstand, the making of a gypsum torso, support made out of plexiglas and polycarbonte and athree dimensional mount on a board.
